WordPress vs a custom build
We build custom sites, so read this with that in mind. It is also why the cases where WordPress wins are stated plainly below rather than glossed over: a studio that claims its own approach suits every business is not being straight with you.
The short answer
WordPress is the right answer when you publish a lot of content, need a large ecosystem of ready-made functionality, or have a budget that does not support custom work. A custom build is the right answer when speed, security, distinctiveness, and low ongoing maintenance matter more than plugin availability, and when the site is a commercial asset rather than a brochure.
Which one suits you
- WordPressContent-heavy publishers, organisations needing many third-party integrations that already exist as plugins, and budgets where custom design is genuinely out of reach.
- Custom buildBusinesses competing on quality where the site must not look like anyone else's, sites where speed and security matter commercially, and teams tired of the maintenance treadmill.
- A website builderVery early stage businesses that need something credible online this week and will revisit it later. This is a legitimate answer, not a failure.
Side by side
| WordPress | Custom build | |
|---|---|---|
| Share of the web | Very large, roughly two in five sites | Small by comparison |
| Upfront cost | Lower | Higher |
| Ongoing maintenance | Regular, core plus plugins plus themes | Minimal on a static build |
| Security surface | Database, admin login, plugin ecosystem | No database or admin panel on a static build |
| Speed | Needs active work to be fast | Fast by default |
| Design ceiling | Bounded by theme and page builder | Whatever was designed |
| Functionality | Enormous plugin ecosystem | Built to requirement |
| Who can maintain it | Very many developers | Fewer, but any competent framework developer |
| Content editing | Strong and familiar | Via a headless editor, equally usable |
Where WordPress genuinely wins
It runs a very large share of the web for real reasons. If you publish frequently, the editorial experience is mature and your team probably already knows it. If you need functionality that exists as a plugin, buying it is faster and cheaper than building it. The talent pool is enormous, so you are never dependent on one agency. And the entry cost is genuinely lower, which matters when a custom build is simply out of reach. Any studio that dismisses all of that is arguing for its own commercial interest rather than yours.
Where it costs you, and the cost is ongoing
The flexibility that makes WordPress powerful is also its liability. Every plugin is code from a third party running on your site, and most compromises exploit an out-of-date component rather than anything sophisticated. Plugins conflict, updates break things, and performance degrades as more are added. None of this is fatal, and a well-maintained WordPress site is fine. But the words well-maintained are carrying the weight, and someone has to do the maintaining month after month, which is the cost that never appears in the original quote.
What a custom build actually changes
A statically generated custom site has no database to inject, no admin panel exposed to the internet, and no plugin ecosystem to keep patched. Pages are pre-built files served from an edge network, so they load in a fraction of the time and stay fast without ongoing tuning. Content is still editable through a headless editor that your team uses exactly like a CMS. The trade-offs are real and worth stating: structural changes need a developer, functionality has to be built rather than installed, and the upfront cost is higher.
Market cost, so you can judge a quote
New Zealand market ranges in 2026 put template-based sites at roughly $1,000 to $4,000, custom-designed business websites at roughly $2,500 to $10,000, and larger custom builds higher again. Maintenance commonly runs from about $50 to $150 a month for basic hosting and updates, and from about $200 to $800 for fuller care. Those are published market figures rather than our prices, and every project is scoped individually. What they are useful for is recognising a quote that sits far outside the market in either direction and asking why.
Common questions
No. WordPress can rank extremely well and has strong SEO tooling available. The common problems are indirect: slow loading from plugin accumulation, bloated markup from page builders, and duplicate URLs from archive and taxonomy pages. All are fixable, but they need attention rather than happening correctly by default.
